IceCube -状态和最新结果

IceCube - status and recent results

A. Karle

摘要:

2011年5月,拥有1立方公里仪器体积的IceCube中微子天文台开始全面运作,86根弦上有5160个传感器,162个IceTop探测器上有324个传感器。探测器的操作和校准的微调仍在进行中,同时获得远高于$98\%$的非常高的反射率。新的分析技术依赖于否决技术,以增强对大气μ子和中微子背景的排斥。我们将给出一个概述最近的结果,包括技术的搜索开始的轨道和一些评论的天体物理证据的能量超过30 TeV的中微子。

英文摘要:

In May 2011, the IceCube neutrino observatory with one cubic kilometer instrumented volume started full operation with 5160 sensors on 86 strings and 324 sensors on 162 IceTop detectors. The fine-tuning of operation and calibration of the detector is still in progress while a very high uptime of well above $98\%$ is obtained. New analysis techniques rely on veto techniques for enhanced rejection of atmospheric muon and neutrino backgrounds. We will give an overview of recent results including the techniques of searching for starting tracks and some comments on the reported evidence of astrophysical neutrinos at energies above 30 TeV.
